/**
 * @file
 * This file contains tests for the Update Manager module.
 *
 * The overarching methodology of these tests is we need to compare a given
 * state of installed modules and themes (e.g., version, project grouping,
 * timestamps, etc) against a current state of what the release history XML
 * files we fetch say is available. We have dummy XML files (in the
 * modules/update/tests directory) that describe various scenarios of what's
 * available for different test projects, and we have dummy .info file data
 * (specified via hook_system_info_alter() in the update_test helper module)
 * describing what's currently installed. Each test case defines a set of
 * projects to install, their current state (via the 'update_test_system_info'
 * variable) and the desired available update data (via the
 * 'update_test_xml_map' variable), and then performs a series of assertions
 * that the report matches our expectations given the specific initial state and
 * availability scenario.
